Fixed bug #4
[Note: I'm applying this patch since it's a cleaner version of what's already implemented, and supports this controller on older kernels. I'll ask to make sure this doesn't break on the new kernels where it's no longer necessary]

Subject: SDL Patch
Hey, Ryan.
I submitted the following patch about a year ago. It's just a simple
patch for the linux port, to make multiple joysticks each appear to SDL
as their own device, if they are on the same USB port (specifically,
these guys
<http://www.consoleplus.co.uk/product_info.php?pName=super-joybox-5-quad-joypad-converter>,
which allow 4 Playstation2 controllers to be accessed via a single USB
port). Without this patch, SDL pretty much drops the ball, and reports
that there are 4 joysticks available when less than that number are
plugged in.
My work built upon the work of another person with the same device. When
I submitted the patch to the list, he tested it, but it didn't work for
him, so the patch was never accepted. Maybe about 3 times in the past
year, I've tried to email the guy, to see if he couldn't run my new
version, complete with debug code to diagnose the problem he was having.
He never got back to me.
So, I'm attaching the patch. I wish I knew why it didn't work for him,
but I've been using it for the last year with no problems. Let me know
if you need any more information, or have any ideas as to how I could
test it. I'd like to see it in the tree, but I want to make sure it works.

================================================================= Patch version 0.9 of SDL(Simple DirectMedia Layer) for Nano-X API ================================================================= Authors: Hsieh-Fu Tsai, clare@setabox.com Greg Haerr, greg@censoft.com This patch is against SDL version 1.2.4. It enhances previous patch 0.8 by providing direct framebuffer access as well as dynamic hardware pixel type support, not requiring a compile-time option setting for different framebuffer modes. Tested against Microwindows version 0.89pre9. Older Microwindows versions =========================== If running on a version older than Microwindows 0.89pre9, the following items might need to be patched in Microwindows. 1. Patch src/nanox/client.c::GrClose() It fixes the client side GrClose(). In the original version, GrOpen() can only be called once. When the GrOpen() is called at the second time, the program will terminate. In order to prevent this situation, we need to insert "nxSocket = -1" after "close(nxSocket)" in GrClose(). If you do not have this problem, you may skip this step. 2. Patch src/nanox/clientfb.c to return absolute x,y coordinates when using GrGetWindowFBInfo(). Copy the version 0.89pre9 of src/nanox/clientfb.c to your system, or configure using --disable-nanox-direct-fb. ============= Quick Install ============= 1. ./configure --disable-video-x11 --disable-video-fbcon \ --enable-video-nanox \ --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 2. make clean 3. make 4. make install (as root) ============ Nitty-gritty ============ --enable-nanox-direct-fb Use direct framebuffer access --enable-nanox-debug Show debug messages --enable-nanox-share-memory Use shared-memory to speed up When running multi-threaded applications using SDL, such as SMPEG, set THREADSAFE=Y in Microwindows' config file, to enable GrXXX() system call critical section support. ============================================= Some programs can be used to test this patch. ============================================= 1. http://www.cs.berkeley.edu/~weimer/atris (a tetris-like game) 2. http://www.libsdl.org/projects/newvox/ 3. http://www.libsdl.org/projects/xflame/ 4. http://www.libsdl.org/projects/optimum/ 5. http://www.gnugeneration.com/software/loop/ 6: http://www.lokigames.com/development/smpeg.php3 (SMPEG version 0.4.4) ========= Todo List ========= 1. Create hardware surface 2. Create YUVOverlay on hardware 3. Use OpenGL 4. Gamma correction 5. Hide/Change mouse pointer 6. Better window movement control with direct fb access 7. Palette handling in 8bpp could be improved ===================== Supporting Institutes ===================== Many thanks to go to Setabox Co., Ltd. and CML (Communication and Multimedia Laboratory, http://www.cmlab.csie.ntu.edu.tw/) in the Department of Computer Science and Information Engineering of National Taiwan University for supporting this porting project.
